The present invention includes a frame, which is sequentially provided with a first assembly section, a second assembly section, a third assembly section, a fourth assembly section, and a debugging section. The base moves in a step-by-step relay along each assembly section and completes the assembly of a conductive component, a swing component, a reset component, and a trigger component. The debugging section then adjusts the swing amplitude of the swing component so that the swing component is electrically connected to the trigger component through the conductive component when it swings to a preset posture.

Description

Technical Field

[0001] The present invention relates to the field of elevators, and in particular to a production line for producing roller switches. Background Art

[0002] Elevator roller switches can trigger switching after an object moves into position and impacts it, thus monitoring the displacement of the target. Existing roller switches consist of a base and a movable trigger portion that can be impacted by the object. Existing production lines employ multiple manual assembly stations to separately install the base and its conductive, swinging, reset, and trigger components. This not only places high demands on the skills of workers at each station, but also easily impacts production line capacity due to differences in assembly efficiency between stations, resulting in lower production efficiency. This also increases labor costs, which in turn increases processing costs. Furthermore, deviations in assembly operations by workers can lead to inconsistent product quality, resulting in lower product quality. Summary of the Invention

[0003] In order to address the shortcomings of the existing technology, the present invention provides a production line for producing roller switches. By setting a first assembly section, a second assembly section, a third assembly section, a fourth assembly section and a debugging section, the conductive component, the swing component, the reset component and the trigger component are completed in sequence and the swing amplitude of the swing component is adjusted, thereby forming a roller switch that meets production requirements. It can effectively improve assembly efficiency and ensure assembly quality, and can also reduce labor costs by reducing the number of assembly workers, thereby improving the user experience.

[0004] The present invention is achieved in the following manner: a production line for producing roller switches, comprising a frame, the roller switch comprising a base and a conductive component, a swinging component, a reset component, and a trigger component arranged on the base. The swinging component is swung by an external force and drives the conductive component to contact and electrically connect with the trigger component after deformation, so that the reset component is deformed by the force and accumulates a preload force to drive the swinging component to reset. The frame is sequentially provided with a first assembly section for assembling the conductive component, a second assembly section for assembling the swinging component, a third assembly section for assembling the reset component, a fourth assembly section for assembling the trigger component, and a debugging section for adjusting the swinging component. The base moves in a step-by-step relay along each assembly section and completes the assembly of the conductive component, the swinging component, the reset component, and the trigger component. The debugging section then adjusts the swing amplitude of the swinging component so that the swinging component is electrically connected to the trigger component through the conductive component when it swings to a preset posture. By setting up a first assembly section, a second assembly section, a third assembly section, a fourth assembly section, and a debugging section, the conductive component, the swing component, the reset component, and the trigger component are sequentially completed, and the swing amplitude of the swing component is adjusted. This creates a roller switch that meets production requirements. This not only reduces processing costs by reducing the number of workers, but also ensures consistent product quality through assembly on the production line, improving assembly efficiency, increasing product qualification rates, and thus enhancing the user experience. In addition, the roller switch structure is used to distribute installation tasks to each assembly section on the production line, effectively simplifying assembly steps, thereby shortening the production line length, improving assembly efficiency and reducing energy consumption. It also simplifies the equipment structure by reducing the assembly difficulty, thereby reducing equipment production costs.

[0005] Preferably, the swing assembly includes a limit bolt which is arranged at the end of the base and can be raised and lowered and adjusted, and a swing member connected to the base through a rotating shaft. The swing member is provided with a roller for receiving external force and a linkage hole for a spring to pass through. The swing member swings and is positioned by the limit bolt to limit the swing member to swing within a preset range. The conductive assembly includes a connecting seat fixed to the base and a spring fixed to the connecting seat. The fixed end of the spring is fixed to the base, and the movable end passes through the linkage hole and is swingably suspended above the trigger assembly. The reset assembly includes a reset spring clamped between the base and the swing member. The limit bolt is used to limit the swing range of the swing part, ensuring that the swing part can swing within the preset range; the swing part is used to receive the impact force of the object component and drive the spring piece to deform, ensuring that the spring piece can switch between the trigger state in which it is in contact with the trigger component and the disconnected state when it is detached from the trigger component; the linkage hole not only provides a passage space for the spring piece, but also has the effect of squeezing and deforming the spring piece, thereby allowing the spring piece to switch between the trigger state and the disconnected state; the reset spring can reset the swing part, so that the swing part can be reset when it is detached from the object component, thereby facilitating the reset of the spring piece.

[0006] Preferably, the first assembly section includes a first front assembly part that grabs the connecting seat from the corresponding feed tray and installs it on the base, a first middle assembly part that grabs the spring piece from the corresponding feed tray and installs it on the base, and a first rear assembly part that grabs the fastener from the corresponding feed tray and screws it on the base. The fixed end of the spring piece is screwed and locked on the base by the fastener passing through the connecting seat. The first front assembly part is used to install the connecting seat on the base, and then the spring piece is grabbed by the first middle assembly part. Finally, the fixed end of the spring piece, the connecting seat and the base are fixed to each other by the fastener provided by the first rear assembly part, ensuring that the relative positions of the three are fixed, which is convenient for transportation to the subsequent assembly area of ​​the rear production line. The conductive component is installed on the base before the swing component, ensuring that there is a larger assembly operation space when installing the conductive component, and preventing the swing component from occupying the assembly operation space.

[0007] Preferably, the first central assembly part includes a first gripper assembly, which includes a first slide rail, a first lifting member sliding along the first slide rail, and a first clamp arranged on the first lifting member. After the first clamp grabs the spring piece in the corresponding feed tray, it moves horizontally along the first slide rail to the top of the corresponding base and cooperates with the base to clamp the spring piece, so that the first rear assembly part can install the fastener. The first clamp is used to grab the spring piece. The first clamp can firmly clamp the spring piece and effectively avoid the fixed end of the spring piece to ensure that the spring piece is transported in a preset posture and preset path. After moving into place, it will not affect the fit between the spring piece and the connecting seat, ensuring the installation accuracy of the spring piece, and will not block the connection of the fastener, ensuring the reliability of the spring piece connection. The first slide rail can guide the first lifting member to move horizontally, so that the first clamp can move back and forth between the feed tray where the spring piece is placed and the base where the conductive component is assembled and transport the spring piece. The first lifting assembly can drive the first clamp to perform lifting operations. It can not only grab the spring piece at the corresponding feed tray and then separate it from the feed tray by rising, but also move it above the connecting seat by descending to accurately install the spring piece.

[0008] Preferably, the second assembly section includes a stop assembly portion for threading a stop bolt with a stop nut onto the base, a second front assembly portion for grabbing the swinging member from the corresponding feed tray and mounting it to the base, and a second rear assembly portion for riveting the fixed shaft. The swinging member is installed so that the movable end of the spring clip passes through the linkage hole and is exposed above the trigger assembly, allowing the movable end to switch and reset between a triggered state (engaged with the trigger assembly) and a disconnected state (disengaged from the trigger assembly) under the action of the swinging member. The swinging assembly is assembled after the conductive assembly is installed, preventing interference with the conductive assembly and ensuring that the swinging member and the spring clip are properly installed and linked to each other to achieve the corresponding function of the roller switch. The stop assembly portion installs the stop bolt onto the end of the base before the swinging member, preventing the swinging member from interfering with the stop bolt installation. The second front assembly portion is used to install the swinging member onto the base and ensure that the spring clip is inserted into the linkage hole, allowing the spring clip to synchronize with the swinging member and switch between the triggered and disconnected states.

[0009] Preferably, the second front assembly part includes an operating table for receiving the transfer base, a second gripper assembly for grabbing and conveying the swinging member, and a lever assembly for vertically lifting the spring. When the operating table receives the base and moves it to the assembly station, the lever assembly is horizontally inserted between the spring and the base and pushes the movable end of the spring upward. The second gripper assembly moved to the assembly station drives the swing to move horizontally and the movable end of the spring passes horizontally through the linkage hole and then falls and overlaps the base, so as to assemble between the base and the swing to form a mounting hole for the shaft to pass through. The operating table is used to fix the base and ensure that the base and the swing are accurately assembled. The operating table can be translated by the driving member so that the spring can be translated and inserted into the linkage hole under the drive of the base; the second gripper assembly is used to grab the swing in the corresponding feed tray and transfer it to the operating table, and adjust the posture and position of the swing to ensure that the swing, base and spring are assembled into a preset state, effectively improving assembly efficiency and assembly accuracy; the lever assembly can adjust the posture of the spring when installing the swing to ensure that the spring can be smoothly inserted into the linkage hole.

[0010] Preferably, the lever assembly includes a rod body, a third lifting member that drives the rod body to move vertically, and a horizontal driving member that drives the third lifting member to move horizontally. The horizontal driving member drives the rod body to move horizontally between a lower station where it is inserted into the gap between the base and the spring piece and an idle station where it is horizontally separated from the base along a direction perpendicular to the base conveying direction through the third lifting member. The third lifting member drives the rod member located at the lower station to be lifted to the upper station, so that the movable end of the spring piece is tilted upward to separate from the trigger assembly and allow the linkage hole to be horizontally sleeved. The rod body can be switched among an idle position detached from the operating table, a lower position for inserting the spring clip, and an upper position for lifting the movable end of the spring clip in cooperation with the third lifting member and the horizontal driving member. It can avoid the operation of taking and placing the base on the operating table at the idle position, prepare to lift the movable end of the spring clip at the lower position, and lift the movable end of the spring clip when switching to the upper position, so that the movable end of the spring clip can be easily inserted into the linkage hole after being tilted upward and detached from the trigger component, effectively reducing the difficulty of assembly and improving the accuracy of assembly.

[0011] Preferably, the second gripper assembly includes a second slide rail spanning between the corresponding feed tray and the assembly station, a second clamp sliding along the second slide rail, and a shift block for adjusting the position of the swinging member. The second clamp is slidably mounted on the second slide rail via a second lifting member, rotatably clamping the swinging member at the corresponding feed tray and adjusting its position via the shift block when moving along the second slide rail to the assembly station, so that the linkage hole is coaxially arranged with the movable end of the spring lifted by the shift rod. The second lifting member can not only slide along the second slide rail but also drive the second clamp to rise and fall, so that the second clamp has the functions of lifting and falling and horizontal movement, facilitating the grasping of the swinging member in the corresponding feed tray and the lowering and overlapping of the spring after the spring is inserted through the linkage hole, thereby improving assembly accuracy. The second clamp can accurately clamp the swinging member, effectively avoiding the linkage hole, preventing the linkage hole from being blocked by the second clamp and preventing the spring from being inserted, and effectively avoiding the base, ensuring that the swinging member can accurately overlap the base and form a mounting hole for the shaft to be inserted. The shifting block is movably arranged on the second clamp, and plays a role in adjusting the posture of the swinging member clamped by the second clamp, ensuring that the axis of the linkage hole is arranged horizontally and accurately sleeved on the movable end of the spring piece.

[0012] Preferably, the third assembly section includes a spreader and a conveying portion that can compress the reset spring and feed it between the swing member and the base. The spreader drives the swing member to swing and separate from the base to form an installation channel. After the compressed reset spring is installed in place through the installation channel, it detaches from the conveying portion, allowing the reset spring to recover its deformation and push the swing member to reset. The conveying portion can feed the clamped and compressed spring into the installation channel formed between the swing member and the base, and after installation, it drives the swing block to reset by recovering its own deformation, thereby switching the spring clip between the triggered state and the disconnected state. The spreader is used to increase the width of the installation channel where the reset spring is installed, making it easier for the conveying portion to insert the reset spring and ensure installation accuracy.

[0013] Preferably, the fourth assembly section includes a fourth front assembly portion that captures the trigger assembly from the corresponding feed tray and fits onto the base, and a fourth rear assembly portion that drives a fastener through the trigger assembly and screws and locks it to the base. The trigger assembly can contact the conductive component to cooperate with the roller switch to achieve circuit conduction. The fourth front assembly portion captures the interference assembly and mounts it to the base. The fourth rear assembly portion captures the fastener and, after passing through the interference assembly secured by the fourth front assembly portion, screws and locks it to the base, thereby securing the interference assembly to the base via the fastener.

[0014] Preferably, the debugging section includes a fixing table for fixing the base, a positioning member for clamping and fixing the swinging member, and a wrench for driving the limit bolt to rotate. The swinging member is clamped and fixed by the fixing table and the positioning member so that a preset angle is formed between the swinging member and the base. The wrench drives the limit bolt to rotate and contact the swinging member so that the swinging member can swing within a preset range. The fixing table is used to fix the base so that the relative position of the base is fixed. The positioning member is used to adjust the posture of the swinging member so that the angle between the swinging member and the base reaches the upper limit of the swing amplitude and is positioned. The wrench is used to drive the limit bolt to rise and contact the swinging member, ensuring that the angle between the swinging member and the base reaches the upper limit of the swing amplitude when the swinging member contacts the limit bolt, thereby ensuring that the triggering timing of the roller switch and the swing amplitude are consistent, thereby improving the product qualification rate.

[0015] The present invention has the following outstanding beneficial effects: by providing a first assembly section, a second assembly section, a third assembly section, a fourth assembly section, and a debugging section, the conductive component, the swing component, the reset component, and the trigger component are sequentially completed, and the swing amplitude of the swing component is adjusted, thereby forming a roller switch that meets production requirements. This can not only reduce processing costs by reducing the number of workers, but also ensure consistent product quality through assembly on the production line, improve assembly efficiency, increase product qualification rate, and thus enhance the user experience. In addition, the structure of the roller switch is used to distribute the installation tasks of each assembly section on the production line, which can effectively simplify the assembly steps, thereby shortening the production line length, improving assembly efficiency and reducing energy consumption. It can also simplify the equipment structure by reducing the difficulty of assembly, thereby reducing the equipment production cost. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The essential features of the present invention will be further described below with reference to the accompanying drawings and specific implementation methods.

[0024] like Figure 1 、 2 A production line for producing roller switches, as shown in FIG3 , comprises a frame 1 having a first assembly section 12 for assembling a conductive component, a second assembly section 22 for assembling a swinging component, a third assembly section 22 for assembling a reset component, a fourth assembly section 23 for assembling a trigger component 10, and a debugging section 4 for adjusting the swinging component. A base 3 sequentially moves in a step-by-step relay along each assembly section, completing the assembly of the conductive component, the swinging component, the reset component, and the trigger component 10. The debugging section 4 then adjusts the swing amplitude of the swinging component so that the swinging component is electrically connected to the trigger component 10 via the conductive component when it swings to a preset position. By providing the first assembly section 12, the second assembly section, the third assembly section 22, the fourth assembly section 23, and the debugging section 4, the conductive component, the swinging component, the reset component, and the trigger component 10 are sequentially assembled, and the swing amplitude of the swinging member 6 is adjusted. Thus, a roller switch 2 that meets production requirements is produced. This reduces processing costs by reducing the number of workers required, ensures consistent product quality through assembly on the production line, improves assembly efficiency, increases product qualification rate, and thus enhances the user experience.

[0025] In actual operation, the roller switch 2 includes a base 3 and a conductive component, a swing component, a reset component and a trigger component 10 (such as Figure 6 As shown), the swing component is swung by the external force and drives the conductive component to contact and electrically connect with the trigger component 10 after deformation, so that the reset component is deformed by the force and accumulates the preload force that drives the swing component to reset.

[0026] Specifically, the swinging assembly includes a limit bolt 5 which is arranged at the end of the base 3 and can be raised and lowered and adjusted, and a swinging member 6 connected to the base 3 through a rotating shaft 25. The swinging member 6 is provided with a roller for receiving external force and a linkage hole 9 for the spring piece 7 to pass through. The swinging member 6 swings and is positioned by the limit bolt 5 to limit the swinging member 6 to swing within a preset range. The conductive assembly includes a connecting seat 8 fixed to the base 3 and a spring piece 7 fixed to the connecting seat 8. The fixed end of the spring piece 7 is fixed to the base 3, and the movable end passes through the linkage hole 9 and is swingably suspended above the trigger assembly 10. The reset assembly includes a reset spring 11 clamped between the base 3 and the swinging member 6. The middle part of the bottom surface of the swing member 6 can be vertically connected with the middle part of the top surface of the base 3 to form a mounting hole for inserting the rotating shaft 25. The limiting bolt 5 and the return spring 11 are respectively arranged on both sides of the rotating shaft 25 to ensure that the swing block is reset under the drive of the return spring 11 and is clamped and positioned at the limit value of the preset swing range by the limiting bolt 5. This not only prevents the swing member 6 from being unable to match and conflict with the object part due to excessive swinging, but also ensures that the return spring 11 is always in a compressed state, thereby ensuring that the return spring 11 is stably clamped between the swing member 6 and the base 3.

[0027] In actual operation, the spring clip 7 and the trigger assembly 10 are arranged on the same side of the rotating shaft 25, which facilitates the deformation of the spring clip 7 under the drive of the swing member 6 and realizes the switching between the triggered state and the disconnected state. When the spring clip 7 and the return spring 11 are arranged on the same side of the rotating shaft 25, the rolling switch is a normally open switch. The spring clip 7 can be separated from the trigger assembly 10 under the action of the return spring 11 and remain in the disconnected state for a long time without being affected by external forces. When the limit bolt 5 and the return spring 11 are arranged on the same side of the rotating shaft 25, the rolling switch is a normally closed switch. The spring clip 7 can contact the trigger assembly 10 under the action of the return spring 11 and remain in the triggered state for a long time without being affected by external forces.

[0028] After understanding the structure and working principle of the roller switch 2, the installation sequence of the components in the roller switch 2 can be reasonably arranged, and then appropriate installation tasks can be assigned to each assembly section, effectively simplifying the assembly steps, thereby shortening the length of the production line. This can not only effectively improve assembly efficiency and reduce energy consumption, but also simplify the equipment structure by reducing the assembly difficulty, thereby reducing the purchase cost of components in the production line, and reducing the error rate by reducing the assembly difficulty, thereby improving the product qualification rate.

[0029] In actual operation, the frame 1 is provided with a conveyor line for relaying the base 3. Along this conveyor line, a first assembly section 12 for assembling the conductive component, a second assembly section for assembling the swing component, a third assembly section 22 for assembling the reset component, a fourth assembly section 23 for assembling the trigger component 10, and a debugging section 4 for adjusting the swing component are sequentially arranged. The conductive component is assembled before the swing component, leaving the open space above the base 3 as assembly space. This effectively prevents the prior assembly of the swing member 6 from interfering with the installation of the conductive component, effectively reducing assembly difficulty and simplifying the structure of the first assembly section 12. The swing component is assembled before the reset component, allowing the reset spring 11 to be clamped and secured by the base 3 and the swing member 6 upon installation, effectively preventing the base 3 from being unable to position the reset spring 11 due to prior installation of the reset spring 11. The debugging section 4 is set at the end of the conveying route to debug the assembled roller switches 2 to ensure that the roller switches 2 produced by the production line have the same swing amplitude of the swing member 6 and the same state switching timing of the spring 7, so that the roller switches 2 have the same usage accuracy and effect, which is convenient for large-scale production and use.

[0030] In actual operation, the base 3 that moves in a step-by-step relay along the conveying line is assembled through the following steps:

[0031] In the first step, the feed tray provides a base 3 at the head end of the conveyor line, so that the base 3 can be moved along the conveyor line at equal intervals. By increasing the distance between adjacent bases 3, the necessary preparation time for the installation of each component is provided;

[0032] In the second step, the connecting seat 8 is assembled by the first front assembly part. The connecting seat 8 is provided with a buckle groove. The corresponding feed tray provides the first front assembly part with the connecting seat 8 adjusted to a preset posture. The first front assembly part grabs the connecting seat 8 and after being transferred to the position, it is fixed on the base 3 through the buckle groove. The assembly reliability is improved by increasing the contact area between the connecting seat 8 and the base 3;

[0033] In the third step, the spring piece 7 is assembled by the first central assembly part. The corresponding feed tray can provide the first central assembly part with the spring piece 7 adjusted to a preset posture. The first clamp grabs the spring piece 7 and, after being transferred to the top of the base 3, drops it down and overlaps it on the connecting seat 8. The first clamp always clamps the spring piece 7 so that the fixed end of the spring piece 7 contacts the connecting seat 8.

[0034] The fourth step is to install the fastener through the first rear assembly part. The first rear assembly part obtains the fastener and screws and locks it with the base 3 after passing through the fixed end of the spring piece 7 and the connecting seat 8 in sequence, so that the spring piece 7 is fixed to the base 3 through the connecting seat 8. During this process, the first clamp clamps and positions the spring piece 7 until the spring piece 7 is screwed and locked by the fastener and then detached, ensuring that the spring piece 7 will not shift during the installation process.

[0035] In the fifth step, the second assembly section receives the product from the first assembly section 12 and installs the limit bolt 5 through the limit assembly part 14. The limit assembly part 14 obtains the limit bolt 5 from the corresponding feed tray and moves it to the base 3 and then rotates it to connect it to the screw hole pre-opened on the base 3;

[0036] In the sixth step, the swing member 6 is assembled through the second front assembly part 15. The operating table 17 receives the base 3 from the limit assembly part 14. The second gripper assembly 18 grabs the swing member 6 adjusted to the preset posture from the corresponding feed tray and transfers it to the operating table 17. The lever assembly 19 moves from the idle position to the lower position and then moves to the upper position to lift the active end of the spring piece 7, thereby facilitating the swing member 6 to be placed on the spring piece 7 through the linkage hole 9. Finally, the swing member 6 is accurately assembled by falling and forms a mounting hole for the rotation shaft 25 to pass through.

[0037] Step 7: Insert the rotating shaft 25 into the mounting hole through the second rear assembly portion 16 and fix it by riveting, so that the swing member 6 is rotatably connected to the base 3 through the rotating shaft 25;

[0038] In the eighth step, the third assembly section 22 receives the product from the second assembly section. The expander is used to drive the swing member 6 to swing and separate its end from the base 3 to form the installation channel. The conveying section receives the return spring 11 from the corresponding feed tray and reduces the height of the spring by squeezing, so that the height of the conveying section with the return spring 11 is lower than the height of the installation channel. The conveying section conveys the return spring 11 to the space between the swing member 6 and the base 3 by passing through the installation channel. After leaving the conveying section, the return spring 11 uses its own elastic force to restore its deformation and drive the swing member 6 to contact the limit bolt 5.

[0039] In the ninth step, the fourth assembly section 23 receives the product from the third assembly section 22, the fourth front assembly part grabs the interference component from the corresponding supply tray and installs it on the end of the base 3, and the fourth rear assembly part obtains the fastener from the corresponding supply tray and screws and locks it on the base 3 after passing through the interference component. During this process, the fourth front assembly part clamps and positions the interference component until the interference component is screwed and locked by the corresponding fastener and then disengaged, ensuring that the interference component will not shift during the installation process;

[0040] In the tenth step, the debugging section 4 receives the product from the fourth assembly section 23. At this time, the product is assembled, the fixed table clamps the fixed base 3, and the positioning part drives the swing member 6 to swing accurately to the limit value of the preset swing range. The limit bolt 5 rotates under the drive of the wrench and contacts the swing member 6, ensuring that the swing member 6 only moves within the preset swing range, ensuring that the roller switch 2 has a uniform swing range and state switching timing.

[0041] The above steps enable the assembly and adjustment of the roller switch 2. Each assembly section and adjacent assembly sections are equipped with independent conveying structures that can match and relay the conveying base 3. These structures include an operating table 17, a fixed table, a conveying belt, a manipulator, etc., which not only serve to convey the base 3 but also form a station for fixing the base 3 within the corresponding assembly section. All of these structures should be considered specific embodiments of the present invention.

[0042] In the actual operation group, the first assembly section 12 includes a first front assembly part that grabs the connecting seat 8 from the corresponding feed tray and installs it on the base 3, a first middle assembly part that grabs the spring piece 7 from the corresponding feed tray and installs it on the base 3, and a first rear assembly part that grabs the fastener from the corresponding feed tray and screws it on the base 3. The fixed end of the spring piece 7 is screwed and locked on the base 3 by the fastener passing through the connecting seat 8. Specifically, the first middle assembly part includes a first gripper assembly 13, which includes a first slide rail, a first lifting member sliding along the first slide rail, and a first clamp set on the first lifting member. After grabbing the spring piece 7 in the corresponding feed tray, the first clamp moves along the first slide rail to the top of the corresponding base 3 and cooperates with the base 3 to clamp the spring piece 7 so that the first rear assembly part can install the fastener. The first clamp is clamped in the middle section of the spring piece 7, which not only ensures that the spring piece 7 is accurately displaced and installed, but also ensures that the fixed top end of the spring piece 7 is exposed, which facilitates the accurate insertion of the corresponding fastener.

[0043] In actual operation, the second assembly section includes a limiting assembly part 14 that screws a limiting bolt 5 with a limiting nut to the base 3, a second front assembly part 15 that grabs the swing member 6 from the corresponding feed tray and installs it on the base 3, and a second rear assembly part 16 for riveting the fixed rotating shaft 25. The swing member 6 is installed in place and the movable end of the spring 7 passes through the linkage hole 9 and is exposed above the trigger component 10, so that the movable end can be driven by the swing member 6 to switch and reset between the trigger state in contact with the trigger component 10 and the disconnected state disengaged from the trigger component 10. The second front assembly part 15 includes an operating table 17 for receiving the transfer base 3, a second gripper assembly 18 for grabbing and conveying the swinging member 6, and a lever assembly 19 for vertically lifting the spring piece 7. When the operating table 17 receives the base 3 and moves to the assembly station, the lever assembly 19 is horizontally inserted between the spring piece 7 and the base 3 and pushes the movable end of the spring piece 7 to move upward. The second gripper assembly 18 moved to the assembly station drives the swinging member 6 to move horizontally and after the movable end of the spring piece 7 horizontally passes through the linkage hole 9, it falls and overlaps the base 3, so as to assemble between the base 3 and the swinging member 6 to form a mounting hole for the rotating shaft 25 to pass through.

[0044] Specifically, the operating table 17 clamps the base 3 and can be displaced along the conveying line, and the second gripper assembly 18 and the lever assembly 19 are placed on both sides of the conveying line.

[0045] First, the second clamp 21 is clamped at the middle of the two side walls of the swing member 6 and transported to the operating table 17 (as shown in FIG. Figure 4 As shown), the swing member 6 is swingably clamped on the second clamp 21. During this process, the shift block swings and adjusts the swing member 6 so that the axis of the linkage hole 9 is set to be horizontal. At the same time, after the base 3 is clamped and positioned by the operating table 17, the shift rod moves horizontally from the idle position whose vertical projection is misaligned with the operating table 17 to the lower position located between the base 3 and the spring plate 7, and then moves upward from the lower position to the upper position and lifts the movable end of the spring plate 7. After the displacement is in place, the swing member 6 is located in front of the base 3, and the movable end of the spring plate 7 faces the linkage hole 9;

[0046] Afterwards, the operating table 17 drives the base 3 to move horizontally toward the swing member 6, so that the movable end of the spring piece 7 passes through the linkage hole 9 and is exposed. Driven by the operating table 17, the base 3 moves to the bottom of the swing member 6, and the lever detaches from the operating table 17 from the upper position and returns to the idle position. The spring piece 7 will overlap the linkage hole 9 due to its own elastic restoring force.

[0047] Finally, the second clamp 21 drives the swing member 6 to move downward and overlap the base 3, and the middle part of the bottom surface of the swing member and the middle part of the top surface of the base 3 face each other to form a mounting hole for inserting the rotating shaft 25.

[0048] The above steps enable precise assembly of the swing member 6 , the spring 7 and the base 3 .

[0049] In actual operation, the lever assembly 19 includes a lever body 20, a third lifting member for driving the lever body 20 to move vertically, and a horizontal driving member (such as a horizontal driving member) for driving the third lifting member to move horizontally. Figure 5 As shown), the horizontal driving member drives the rod body 20 to translate and switch between the lower station where it is inserted into the gap between the base 3 and the spring piece 7 and the idle station where it is horizontally separated from the base 3 along the conveying direction perpendicular to the base 3 through the third lifting member. The third lifting member drives the rod at the lower station to be lifted to the upper station, so that the movable end of the spring piece 7 is tilted upward to separate from the trigger assembly 10 and allow the linkage hole 9 to be horizontally sleeved.

[0050] In actual operation, the second gripper assembly 18 includes a second slide rail spanning between the corresponding feed tray and the assembly station, a second clamp 21 that slides along the second slide rail, and a shift block for adjusting the posture of the swinging member 6. The second clamp 21 is slidably mounted on the second slide rail via a second lifting member. It rotatably clamps the swinging member 6 at the corresponding feed tray and adjusts its posture via the shift block when it moves along the second slide rail to the assembly station, so that the linkage hole 9 is coaxial with the movable end of the spring 7 lifted by the shift rod. The shift block is set on the second clamp 21 and is offset from the swing center of the swing block when clamped by the second clamp 21, facilitating the shift block's ability to drive the swinging member 6 clamped by the second clamp 21 to perform swing adjustment.

[0051] In actual operation, the base 3 with the swing part 6 is flipped and switched to a flat position with the axis of the mounting hole vertical after entering the second rear assembly part 16, which is convenient for the insertion and riveting of the rotating shaft 25. During the processing, the base 3 and the swing part 6 are always clamped and positioned by the corresponding workbench to ensure that the mounting hole is always in a state with the axis vertical.

[0052] In actual operation, the third assembly section 22 includes a spreader and a conveying portion that can compress the reset spring 11 and send it into the space between the swing member 6 and the base 3. The spreader drives the swing member 6 to swing and separate from the base 3 to form an installation channel. After the compressed reset spring 11 is installed in place through the installation channel, it is separated from the conveying portion, so that the reset spring 11 can restore its deformation and push the swing member 6 to reset.

[0053] In practice, fourth assembly section 23 includes a fourth front assembly portion that grabs trigger assembly 10 from the corresponding feed tray and inserts it onto base 3, and a fourth rear assembly portion that drives a fastener through trigger assembly 10 and screws it onto base 3. During installation of trigger assembly 10, swing member 6 is used to tilt spring 7 upward, providing space for the interference assembly and improving assembly convenience.

[0054] In actual operation, the debugging section 4 includes a fixing platform for fixing the base 3, a positioning member for clamping and fixing the swinging member 6, and a wrench for driving the limit bolt 5 to rotate. The swinging member 6 is clamped and fixed by the fixing platform and the positioning member, so that the swinging member 6 forms a preset angle with the base 3. The wrench drives the limit bolt 5 to rotate and contact the swinging member 6, so that the swinging member 6 can swing within a preset range. The bottom end of the limit bolt 5 is threaded into the base 3, and the top surface forms a limit surface that contacts the swinging member 6. The side wall of the limit bolt 5 is exposed, facilitating screw adjustment with the wrench.

[0055] In the actual operation group, the frame 1 includes multiple unit frames, and the first assembly section 12, the second assembly section, the third assembly section 22, the fourth assembly section 23 and the debugging section 4 can be assembled on multiple unit frames respectively, preferably three unit frames, which is convenient for assembly production and disassembly and transportation.

[0056] In this embodiment, the structures used to realize mechanical actions, such as the horizontal driving member, the first lifting member, the second lifting member and the third lifting member, can be realized using equipment such as cylinders, and at the same time, precise guidance can be achieved by using structures such as rails and guide rods, which should all be regarded as specific embodiments of the present invention.
